touch gui element "fader" movement up/down detection?

hi coders, how to do this properly?

pv = get parameter value
v = get value from touch fader movement
if v > last_v
pv = pv + 1
pv = pv - 1

    The naive math would be:

    pv = pv + (v - last_v)

    But that will give you a cumulative error.

    Better would be:

    • when fader is first touched:

      • initial_v = v
      • initial_pv = pv
    • on movement:

      • pv = initial_pv + (v - initial_v)

    (assuming v is the current fader position)

  • exactly what i wanted!:)
    thank you very much @SevenSystems
